After years of debate, the latest animal testing statistics still show a hard split between regulation on paper and what happens in labs. In 2025, large numbers of animals are reported used across toxicity, safety, and biomedical research, even as alternatives and bans expand unevenly. When you line those figures up side by side by purpose and country, the scale and direction of change start to look far more complicated than most headlines suggest.
Key Takeaways
- In 2022, approximately 127.6 million animals were used in experiments worldwide, according to estimates combining regulatory data from multiple countries
- EU Directive 2010/63 bans animal testing for cosmetics since 2013, reducing rabbit uses by 80%
- In 2021, mice accounted for 62% of all animals used in EU labs, totaling about 5.5 million mice
- In the US, 58% of animal experiments in 2022 were for basic biomedical research purposes
- 50-70% of animals in toxicity tests suffer severe pain without analgesics, per HSI analysis
Animal testing has decreased in some regions, while alternatives continue to grow in adoption and impact.
